Breanna, Bre, Sam, Aislyn, and Caleb all are excited to go on Season 2 of the 'Sing Off'. They make it in a few rounds or so until one day a fatal accident happened. Bre forgot the lyrics to their song and they were kicked off. They continued their YouTube channel they started when they joined the 'Sing Off' for a few years until it was time to go their separate ways. They went to different colleges and all started their own thing. Then one day, Breanna meets one of the members of the world famous A Cappella band and the band gets back together. That's when their two worlds collide.

Dylan & Bre are on the journey of their lives when they meet Pentatonix at their college, Texas Performing Arts- College of Fine Arts in Austin. The A Cappella group invites them to be their on tour choreographers after seeing them perform in their show choir club. The invite leads to turns and up hill climbs, but it always keeps them... on their feet.
